The Smiling Man, Joseph's second novel featuring Detective Aidan Waits, is now available in book shops and online.

The Smiling Man reviewed:

'Knox writes electric novels. A major voice in fiction, and a writer of furious talent.' (A.J. Finn, author of The Woman in the Window)

'Knox’s first novel was pedal-to-the-floor stuff, and this is even more powerful. One thing is sure: Knox is no one-hit wonder.' (Barry Forshaw, The Guardian)

'If you liked Sirens, you will love The Smiling Man. Gritty, noir, and packing a punch from the very first page.' (Jane Harper, author of The Dry)

'Written with Knox’s powerful descriptive prose and underpinned with black humour, a plot full of perfectly gathered threads, and a bone-chilling, gut-wrenching intensity, this remarkable thriller is proof of an author with far more than one ‘big’ book to his name.' (Pam Norfolk, Lancashire Post)
